Definitions
- This invention relates to a metal organic chemical vapour deposition (MOCVD) process for depositing silicon doped intermetallic semiconductor compounds.
- MOCVD metal organic chemical vapour deposition
- the element silicon (Si) has been found to be desirable for incorporation as a dopant. Silicon however is exceptionally non-volatile. The low volatility of elemental silicon preempts its direct use in vapor phase growth. This is generally overcome by providing the silicon in the hydride silane (SiH 4 ). A description of the introduction of silicon as a dopant using silane (SiH 4 ) is given in J. Electro- chemical Society 126, No. 7, July 1979, p.1134 to 1142.
- the crystalline material is grown atom by atom epitaxially, several requirements for the silicon source in order that the dopant enter the crystal in such a way that device specifications can be met.
- the dopant must be present over the growing crystal in a concentration or flux that is uniform over the area and remains so for the duration of the growth period, in order to result in a crystal with a controlled doping concentration.
- the source of silicon must be pure since small quantities of impurities can affect device performance.
- the silicon source should also be capable of rapid changes in concentration over the surface of the growing crystal in order to reach both the concentrations and the rates of change of concentrations required for the device structures.
- the invention seeks to provide a source of silicon which is more advantageous than silane (SiH 4 ) in a metal organic chemical vapour deposition process.
- a metal organic chemical vapour deposition process for epitaxially depositing a silicon doped intermetallic semiconductor compound in which a gaseous hydride based silicon compound is used as a source of silicon is characterised by the hydride based silicon compound having a molecule containing at least two silicon atoms.
- a metal organic chemical vapour deposition process for epitaxially depositing a silicon doped intermetallic semiconductor compound is characterised by employing a higher silane gas as a source of the silicon.
- disilane (Si 2 H 6 ) and the higher hydride based silicon compounds when maintained in the gaseous state over a growing intermetallic semiconductor substrate, will serve as a source of silicon dopant in the growing crystal that provides a higher doping efficiency and a more uniform doping distribution yet achieved at a lower temperature than silane (SiH 4 ).
- the higher silane compounds that are gaseous at lower temperatures, up to Si 3 H 8 , and the even higher silane compounds, up through Si 5 H 12 , 5 that can be maintained in the vapor state over the growing crystal are satisfactory dopant sources, with disilane (Si 2 H 6 ) being preferred.
- the 6 growth of the intermetallic crystal can occur at temperatures greater than 500°C and there is no variation in doping efficiency with temperature variation.
- the decomposition of the higher hydride based compounds of silicon takes less energy than the removal of hydrogen atoms from a single silicon atom such as the case in the decomposition of silane (SiH 4 ) and in turn the lower required energy permits efficient doping at lower temperatures, and less temperature sensitivity for uniform growth and doping.
- the graph indicates the influence of growth temperature on electron concentration in gallium arsenide (GaAs).
- This graph provides a comparison of dopant concentration when disilane, (Si 2 H 6 ) is used and when the prior art silane (SiH 4 ) is used under growth conditions of a constant amount of dopant and at a constant growth rate.
- the temperature scale is in both degrees centigrade and reciprocal temperature. From the concentrations shown not only does more silicon enter the growing crystal when disilane is used thereby illustrating enhanced doping efficiency but also disilane doping is seen to be temperature independent.
- the silicon dopant source in a process according to the invention permits control not achieved heretofore in the art.
- the silicon doped GaAs crystal layers produced are characterized by room and low temperature photoluminescence, capacitance profiling and Van der pauw Hall measurements.
- the substrates on which the intermetallic semiconductor crystals are to be grown are positioned on a hot susceptor and are then brought to an elevated temperature of the order of 550°C to 800°C while exposed to the gaseous silicon source.
- an elevated temperature of the order of 550°C to 800°C while exposed to the gaseous silicon source.
- the temperature across the area of the substrates it is common for the temperature across the area of the substrates to vary in the order of ⁇ 10°C.
- a ⁇ 10°C variation in substrate temperature at 650°C would result in a ⁇ 20% variation in silicon dopant incorporation across a substrate so that the doping would not be homogenous.
- a silicon source according to the process of the invention such as disilane (Si 2 H 6 ) is employed, the incorporation of silicon (as shown in the 6 graph) is independent of temperature and a ⁇ 10% temperature variation would have no effect on the doping concentration.
- the process of the invention provides uniform doping even though temperature gradients may occur.
- the doping efficiency is greater which permits higher conductivity device material to be made thereby providing intermetallic semiconductor material capable of meeting a wider range of device specifications.
- one of the difficulties with gaseous sources is that there may be some uncontrollable impurities in the gas and these are carried into the growth chamber. Where the doping efficiency is high as with the present invention, the quantity of gas needed is less and thus the contamination from impurities in the gas is reduced.
- silicon doped gallium arsenide is grown by metal organic chemical vapor deposition with the addition of a small amount of disilane (Si 2 H 6 ) to the gas phase ambient during the growth.
- the disilane (Si 2 H 6 ) is markedly less stable than silane 2 (SiH 4 ), its decomposition by-products do not contaminate the gallium arsenide (GaAs) layers and the silicon enters the growing crystal so efficiently that the amount of dopant gas required at lower growth temperatures is reduced by two orders.
